Argument is correctly passed and prints as expected.
I just found that for some reason in the new config I created for this
work that somehow CONFIG_BOARD_LATE_INITIALIZE was not set, so my board
bringup code was not initialised, so there was no /dev/fb0 for lvgl to use.
Doh!

I'm asking about parameters because if I recall correctly the arguments
were stored on program stack, so I thought of maybe some stack alignment
issue or something similar.
Maybe you can modify lvgldemo_main and place print some message to console
+ sleep(1); in a loop just after it is entered? Not sure if that will give
us much, but worth of trying to get some information.
Best regards,
Petro

Yes (or "music") - so called by
nsh: lvgldemo music
It's a memory-type problem of some sort rather than errors with vars, I
believe.

Just to clarify, when you run lvgldemo from nsh, do you also pass "widgets"
as argument, right?

Having got u-boot to actually do something, I now have a board that

relieved!
As a step towards it booting my own (barely started) app I thought I'd
play around with booting other example apps, and went for lvgldemo.
This works just fine called from the nsh, but crashes very early on if
set as the startup program.
- I have traced it a little way through so know it is calling the
lvgldemo main function. If I don't specify which demo to run in
INIT_ARGS it correctly prompts me that it needs this argument. With it
set to "music" or "widgets" (which both usually work just fine) it
fails.
- I have looked at Alan's (?) video (#047) but nothing I've missed
according to that.
- I changed the lvgldemo stack size from the default 4096 to 65535 and
same behaviour. And done a distclean etc.
- I tried another (much simpler) program (uniqueid) and that runs fine.
Anyone seen anything similar? This is a good time for me to learn any
must-know stuff when it comes to running graphics apps at startup!
